I've recently found a referrer in the apache log on my site. Now, I opened it out of curiosity, since my site is live, but I just started development so I didn't expect it.
Anyway, the site was a pure copy of mine, and after investigation I saw that it resolves to my IP.
I'm on Ubuntu 12.04, Apache 2, drupal 7, don't know what other info can I provide.
My question is: how can I tell apache that it should not serve this site?
Thanks
Edit: forgot to say that I had some bots register to my fresh drupal installation. Also, my domain is a tld, this fake domain is a third level (ie. sub.domain.de)
Odd that someone would point a random DNS name to your system, and that it would be getting hits.. might be worth looking into who owns that domain, if this has happened to other people and what the point is, etc.
Anyway, you can get Apache to stop serving real content for these requests by mapping that
Host
header to a junk virtual host.
